I am using modbus communication supported by Instrument Control Toolbox. The problem is my modbus slave has a user-defined function code 28 and I cannot find a possible way to send the command including the function code 28. The command I want to send should be like "01 28 ...", can anyone remind me of a way to do this?

To be specific, I want to find a matlab function that can send binary data over a modbus object.

The only solution I can think of is to delete the modbus object, create a new serial object and use write() function to communicate.
